POSITION OF THE RCC COMMUNICATIONS ADMINISTRATIONS ON AGENDA ITEMS FOR THE 2019 WORLD RADIOCOMMUNICATION CONFERENCE

(draft, version of 14 September, 2017)

1.1, 1.2, 1.3, 1.4, 1.5, 1.6, 1.7, 1.8, 1.9.1, 1.9.2, 1.10, 1.11, 1.12, 1.13, 1.14, 1.15, 1.16, 2, 4, 7, 8, 9.1.1, 9.1.2, 9.1.3, 9.1.4, 9.1.5, 9.1.6, 9.1.7, 9.1.8, 9.1.9, 9.2, 9.3, 10

Administrations of the participant countries of the Regional Commonwealth in the field of Communications (RCC),



recognizing the need

  • to improve regulation and increase efficiency of radio spectrum and satellite orbits;

  • to establish conditions for the development of radiocommunications and introduction of new radio technologies;

  • to maintain the balance of interests between existing and new allocations to different radiocommunication services;

  • to take into account technical and economic opportunities in the development of radiocommunications within the ITU Member States;

  • to strengthen regional and international cooperation in the development of radiocommunication equipment and systems,

considering

that during studies on agenda items 1.6 (non-GSO FSS), 1.13 (IMT), 1.14 (HAPS) and 9.1 (Issue 9.1.9, Resolution 162 (WRC-15)), it would be reasonable to identify priority and non-overlapping frequency bands for each of these items,

have developed the following position on agenda items for the 2019 World Radiocommunication Conference (WRC-19):

1.1 to consider an allocation of the frequency band 50-54 MHz to the amateur service in Region 1, in accordance with Resolution 658 (WRC-15);


The RCC Administrations consider that during studies on possible allocation of the frequency band 50-54 MHz to the amateur service in Region 1, spectrum requirements for the amateur service shall be identified.

The RCC Administrations consider that, when identifying technical and regulatory conditions for such allocation, protection shall be ensured to the broadcasting service to which this frequency band is allocated on a primary basis, including stations of the broadcasting service in the frequency band 50-54 MHz, regulated by Stockholm-61 and Geneva-89.


1.2 to consider in-band power limits for earth stations operating in the mobile-satellite service, meteorological-satellite service and Earth exploration-satellite service in the frequency bands 401-403 MHz and 399.9-400.05 MHz, in accordance with Resolution 765 (WRC-15);


The RCC Administrations support measures to study this issue and establish emitted power limits for earth stations used for space operation functions in the frequency bands 401-403 MHz and 399.9−400.05 MHz in order to avoid interference to data collection systems in the meteorological-satellite service, Earth exploration-satellite service and mobile-satellite service taking into account the Report ITU-R SA [400 MHz-LIMITS].

The RCC Administrations consider that specified limits resulted from the above-mentioned studies shall not cover the registered in MIFR space systems using frequency bands 401-403 MHz and 399.9-400.05 MHz for space operation functions.


1.3 to consider possible upgrading of the secondary allocation to the meteorological-satellite service (space-to-Earth) to primary status and a possible primary allocation to the Earth exploration-satellite service (space-to-Earth) in the frequency band 460-470 MHz, in accordance with Resolution 766 (WRC-15);


The RCC Administrations consider that there is a need to harmonize frequency allocations used by data collection systems (DCS) in the meteorological-satellite service and the Earth exploration-satellite service.

The RCC Administrations support studies on this issue, in particular, for the purpose of establishing the constraints for space stations, which ensure acceptable interference level.

However upgrading the secondary allocation to the meteorological-satellite service (space-to-Earth) to a primary status and a primary allocation to the Earth exploration-satellite service (space-to-Earth) in the frequency band 460-470 MHz are possible under the following conditions:

- The protection of the terrestrial services to which the frequency band 460-470 MHz is allocated on a primary basis, which ensure acceptable interference level;

- The proposed measures for the protection of the terrestrial services will not impose additional constraints on the existing satellite systems and the networks operated within meteorological-satellite service and the Earth exploration-satellite service;

- Maintaining priority of the meteorological-satellite service over the Earth exploration-satellite service.


1.4 to consider the results of studies in accordance with Resolution 557 (WRC-15), and review, and revise if necessary, the limitations mentioned in Annex 7 to Appendix 30 (Rev. WRC-12), while ensuring the protection of, and without imposing additional constraints on, assignments in the Plan and the List and the future development of the broadcasting-satellite service within the Plan, and existing and planned fixed-satellite service networks;


The RCC Administrations support studies on possible revisions to the limitations in Annex 7 to Appendix 30 (Rev. WRC-12), while ensuring the protection of, and without imposing additional constraints on, BSS assignments in the Plan and in the List and FSS networks.

The RCC Administrations support the deletion of the following limitations

Atlantic Region:


  • Limitation A1 (part a) (No assignments in the Region 1 List in the frequency band 11.7-12.2 GHz further west than 37.2°W);

  • Limitation A2a (No modification in the Region 2 Plan in the frequency band 12.5-12.7 GHz further east than 54°W);

  • Limitation A2b (No modification in the Region 2 Plan in the frequency band 12.2-12.5 GHz further east than 44°W).

Pacific Region:

  • Limitation A1 (part b) (No assignments in the Region 1 List in the frequency band 11.7-12.2 GHz further east than 146°E);

The RCC Administrations consider the possibility to delete the following limitation

Pacific Region:



  • Limitation A2c (No modification in the Region 2 Plan in the frequency band 12.2-12.7 GHz further west than 175.2°W).

The RCC Administrations continue studies on suppression/revision of the following limitations:

  • Limitation A3 (part a) (No assignments in the Regions 1 & 3 List outside specific allowable portions of the orbital arc between 37.2°W and 10°E);

  • Limitation A3 (part b) (Max. e.i.r.p. of 56 dBW for assignments in the Regions 1 & 3 List at specific allowable portions of the orbital arc between 37.2°W and 10°E);

  • Limitation A3 (part c) (Max. power flux density of -138 dB(W/(m2·27 MHz)) at any point in Region 2 by assignments in List located at 4°W and 9°E);

  • Limitation B (Required agreement of administrations having assignments to space stations in the same cluster when an administration may locate a satellite within this cluster).

The RCC Administrations consider that the proposed revisions of criteria and provisions of Appendix 30 (Rev. WRC-15), other than of Annex 7, are beyond the scope of the studies in accordance with Resolution 557 (WRC-15).
